Given Function: We are given a piecewise function f(x) with two cases:1. f(x)=−6 for all x except when x=12. f(x)=6 when x=1Since we need to find f(−6), we look at the first case because −6 is not equal to 1.
Find f(−6): We apply the first case of the piecewise function to find f(−6).f(−6)=−6 because x is not equal to 1.
